Issued 2015-01
Steel, Corrosion-Resistant, Bars, Wire, Forgings, Tubing, and Rings
16Cr - 4.0Ni - 0.30Cb - 4.0Cu

RATIONALE
AMS5622/H1025 is a new specification for purchase of corrosion-resistant steel product in the solution and precipitation
heat treated condition.
1. SCOPE
1.1 Form
This specification covers a corrosion-resistant steel product in the solution and precipitation heat treated (H1025) condition.
1.1.1 The aged product may be supplied directly by a mill or by a producer other than the mill. The latter would be
accomplished by precipitation heat treatment of solution treated material previously certified to AMS5622. The
entity assuming responsibility for the aging operation is designated the producer of AMS5622/H1025.
1.1.2 This specification covers product up to 8.0 inches (203 mm) in diameter or least distance between parallel sides,
and forging stock of any size (See 8.2).
1.2 Application
These products have been used typically for parts requiring corrosion resistance and high strength up to 600 °F (316 °C)
with good ductility and strength in the transverse direction in large section sizes, but usage is not limited to such applications
(See 8.1).
1.3 Classification
Melting practice classification shall be in accordance with AMS5622.
2. APPLICABLE DOCUMENTS
The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the
extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is
specified. When the referenced document has been cancelled and no superseding document has been specified, the last
published issue of that document shall apply.

Shall be in accordance with AMS5622.
3.3 Condition
Shall be in accordance with AMS5622, and the following:
3.3.1 The product shall be supplied in the precipitation hardened (H1025) heat treat condition.
3.3.2 If straightening is performed after precipitation hardening heat treatment, product shall be stress relieved by heating
to 925 °F (496 °C) and soaking for at least 1 hour plus one 1 additional for each inch (25 mm) of thickness or fraction
thereof greater than 1 inch (25 mm). When load thermocouples are used, the soaking time shall be at least 1 hour.
3.3.3 Bars shall not be cut from plate (Also see 4.3.3).

option, except acceptance testing and criteria shall be as specified in 3.5.1.3. Precipitation heat treatment
furnaces shall have Type B instrumentation.
3.4.1.2 When the product is precipitation heat treated by an entity other than the mill producer of the AMS5622-certified
product, the heat treatment source shall be accredited by a recognized industry agency for stainless steel heat
treatment acceptable to the purchaser.
3.5 Properties
3.5.1 All products shall conform to the following requirements:
